ZX Spectrum is a simple 8-bit computer sold from 1982 until the late 80s. Its design, though aged today, is very similar and has comparable capabilities to modern microcontrollers found in Arduino-type kits: it is equipped with an 8-bit processor, 48 KB of RAM, a built-in BASIC language, and an edge connector to which external peripherals can be connected.
The original 1980s version of the ZX Spectrum however, has several drawbacks: it only works with televisions, programs are loaded from a cassette recorder, and the computer doesn’t even have a power switch or a RESET button.
However…
…all these imperfections have been eliminated in modern clones of this computer. Modern equivalents, 100% compatible with the ZX Spectrum, additionally feature:
– RCA (cinch) or SCART video output
– mass storage
– an SD card for saving programs
– the ESXDOS operating system for easier file operations
– up to 10 times lower power consumption, allowing them to be battery-powered
Thanks to this, modern ZX Spectrum clones have enormous educational potential for anyone who wants to start their adventure with automation and microcontrollers.
And besides… let’s remember that the ZX Spectrum is also an entertainment platform with thousands of great games! All are available online as .TAP or .TZX files.
